Controller generator is creating duplicates entries in config/router.py

[rszamszur]

• I have searched the issues of this repo and believe that this is not a duplicate.

Describe the bug

$ fastapi-mvc generate controller demo method1 method2:post
[INFO] Running controller generator
(.venv) 
$ fastapi-mvc generate controller demo method1 method2:post
[INFO] Running controller generator
$ cat test_app/config/router.py 
"""Application routes configuration.

In this file all application endpoints are being defined.
"""
from fastapi import APIRouter
from test_app.app.controllers import demo
from test_app.app.controllers import demo
from test_app.app.controllers.api.v1 import ready

router = APIRouter(prefix="/api")

router.include_router(ready.router, tags=["ready"])
router.include_router(demo.router)
router.include_router(demo.router)

Expected behavior

Controller generator should validate if an entry already exists. If --skip flag is provided, don't override; else override.

To Reproduce

Run the same controller generator twice.

Environment

• Python version: 3.9.6
• Operating System: Linux-5.10.106-x86_64-with-glibc2.33
• fastapi-mvc version: 0.10.0

Additional context

This is implemented in controller generator template post_gen_project.py hook.
